ATOS: ATOS :The CEA Tera1000 Bull sequana by Atos enters the TOP500 most powerful supercomputers in the world

· Marks the launch of the second stage of Tera1000 project at CEA,
which heralds
the arrival of exascale supercomputers

* Atos adds a 20thHPC in the TOP500 using a revolutionary BXI technology

Paris, 22 November 2016 - Atos, an international leader in digital services,
and CEA announce that the first Bull sequana equipped with BXI (Bull eXascale
Interconnect) has entered the
TOP500ranking of the most powerful supercomputers in the world. A total of 20
supercomputers developed by Atos are currently ranked in the TOP500 list*.

The Bull sequana supercomputer equipped with BXI is the first "cell" of the
25-petaflop supercomputer that Atos will supply to The French Alternative
Energies and Atomic Energy Commission (CEA) in 2017 as part of the Tera1000
project. Its architecture heralds the next generation of exascale
supercomputers for the 2020s. The first phase of theTera1000 supercomputer at
CEAis currently ranked #55 in the TOP500.

One single cell ranked in TOP500

The system that is ranked in the TOP500 is a single Bull sequana cell,
featuring 85 compute blades interconnected by a BXI network, with a total of
220 Intel® Xeon Phi(TM) 7250 processors, coming to a theoretical peak power
of 670 teraflops[1]. It is developing a Linpack performance of 380.5
teraflops. For the first time in the world, a supercomputer is equipped with
the new generation BXI network developed by Atos. BXI is one of the key
technologies that will eventually enable us to reach exascale level
performances.

Designed and developed in France

Bull sequana supercomputers are produced at the Atos factory in Angers,
France. They are designed based on the worldwide expertise of engineers from
the Atos group, as well as long-standing partnerships with major customers
such as the CEA: the tried-and-tested methodology of co-design aims to
optimise the performance of the simulation code - supercomputer pairing.

As François Geleznikoff, Head of the CEA's Military Applications Division,
says: "Meeting the challenge of exaflops and big data is a major issue for
research, defence and industry, as it opens up a whole field that today
remains unexplored and inaccessible, making it possible for us to not only
understand, but also simulate complex physical phenomena and industrial
systems. In Europe, the CEA, in partnership with Atos, is particularly well
positioned to meet this challenge - both in terms of the expertise of its
teams, and the dynamism of its computing facilities, which are open to all
fields of research and industry."

Philippe Vannier, Executive Vice-President in charge of Big Data&Security and
the Chief Technology Officer in the Atos Group, adds: "Atos is incredibly
proud to see the concrete results of the Tera1000 project. Today we are
taking a major step on the road towards exaflops. Undoubtedly, the
interconnect technologies will provide a crucial contribution in achieving
exaflops performance. With BXI, Atos is confirming its leadership in the
field of supercomputers and beyond in the processing of very large volumes of
data."

The Atos supercomputer 'Santos Dumont' at LNCC in Brazil ranked #364 received
an award from the TOP500 organization as it is the largest supercomputer in
South America.

About
the CEA and the Military Applications Division

The French Alternative Energies and Atomic Energy Commission (CEA) is a public
research organization working in four main areas: defense and security,
nuclear and renewable energies, technological research for industry and
fundamental research. Building on its recognized expertise, the CEA takes
part in implementing cooperation projects with a wide range of academic and
industrial partners. With its 16,000 researchers and employees, it is a major
player in European research and is also expanding its international presence.
The CEA's Military Applications Division ("DAM") takes charge of defence and
security missions. The DAM is responsible for the design, manufacture and
through-life support of the nuclear warheads that equip France's sea- and
airborne deterrence forces and of the nuclear reactors and reactor cores on
French Navy submarines and aircraft carrier. The DAM also contributes to
national and global security through the technical support it provides to the
authorities relative to the prevention of nuclear proliferation and terrorism
in chemical, biological, radiological, nuclear and explosives domains
(CBRN-E) and cybersecurity. For more information, visit: www.cea.fr
